- the other cabinet is a display-side cabinet 2 provided with a display, the front cabinet segment 5 of the manipulation-side cabinet 1 and the rear cabinet segment 7 of the display-side cabinet 2 being connected to each other by the hinge mechanism 3 .
- the front cabinet segment 5 of the manipulation-side cabinet 1 and the rear cabinet segment 7 of the display-side cabinet 2 are connected to each other, so that when the two cabinets 1 , 2 are to be closed with extraneous matter held therebetween, at least the front cabinet segment 6 of the display-side cabinet 2 is not subjected to a spreading force acting to move the segment 6 away from the rear cabinet segment 7 . This obviates the likelihood that a clearance will be created at the joint between the segments 6 and 7 of the display-side cabinet 2 .
- the rear cabinet segment 4 of the manipulation-side cabinet 1 is subjected to a spreading force acting to move the segment 4 away from the front cabinet segment 5 , whereas even if screws 91 are driven into the front segment 5 from outside the rear segment 4 , there arises no problem in respect of design. Accordingly, these segments can be fastened with the screws at a position in the closest proximity to the hinge mechanism 3 . As a result, there is no likelihood that a clearance will be created at the joint between the segments 4 , 5 of the manipulation-side cabinet 1 .
- the front cabinet segment 5 of the manipulation-side cabinet 1 is provided with a pair of annular pieces 51 , 52 projecting from one end thereof and spaced apart from each other
